Abstract

A six celled collapsible carton formed from a single cardboard blank which includes an automatic locking bottom and dividers which extend the entire height of the box. The carton is provided with four L-shaped dividers, two of which further include a central tab, spaced from both the top and bottom edges of the divider, for fixedly connecting an associated alternate divider to form a pair of cross-shaped divider members. One section of each pair of cross-shaped divider members overlaps to form a central wall. The side edge of each overlapping section is provided with a notch for creating an interengagement between the sections to add structural rigidity to the central wall. The side edges of the overlapping sections further include an arcuately shaped portion above the notches to facilitate the interengagement between the sections. The carton can be shipped in a flattened configuration and can be readily erected.

Dependent claims

A collapsible six-cell carton comprising:

opposed side walls and opposed end walls hingedly interconnected at their side edges to form a tubular structure;
two first bottom panels, respectively hingedly connected to the bottom edges of said side walls;
two second bottom panels, respectively hingedly connected to the bottom edges of said end walls, said first and second bottom panels being interengaged to form a bottom for said carton;
two first dividers each of L-shaped configuration respectively hingedly connected to said first bottom panels and disposed perpendicular thereto;
and
two second dividers each of L-shaped congiruation respectively hingedly connected to said second bottom panels and disposed perpendicular thereto, said first and second dividers being of substantially the same height as said carton walls, each of said second dividers including a central cut line defining a tab means, said tab means being spaced from the top and bottom edges of said second dividers, one said tab means for fixedly connecting one said second divider to the adjacent said first divider to form a first cross-like divider member, the other said tab means for connecting the other said second divider to the other said first divider to form a second cross-like divider member, with one portion of each cross-like divider member being disposed in overlapping relation to create a central wall whereby said cross-like divider members cooperate with each other and with said carton walls to form a six-cell configuration.

opposed side walls and opposed end walls hingedly interconnected at their side edges to form a tubular structure;
two first bottom panels, resepectively hingedly connected to the bottom edges of said side walls;
two second bottom panels, respectively hingedly connected to the bottom edges of said end walls, said first and second bottom panels being interengaged to form a bottom for said carton;
a primary cover flap hingedly connected to the top edge of one of said side walls;
two secondary cover flaps each respectively hingedly connected to the top edges of said end walls, said cover flaps being foldable to close the top of said carton;
two first dividers of L-shaped configuration respectively hingedly connected to said first bottom panels and disposed perpendicular thereto;
and
two second dividers each of L-shaped configuration respectively hingedly connected to said second bottom panels and disposed perpendicular thereto, said first and second dividers being of substantially the same height as said carton walls, each of said second dividers including a central cut line defining a tab means, said tab means being spaced from the top and bottom edges of said second dividers, one said tab means for fixedly connecting one said second divider to the adjacent said first divider to form a first cross-like divider member, the other said tab means for connecting the other said second divider to the other said first divider to form a second cross-like divider member, with one portion of each cross-like divider member being disposed in overlapping relation to create a central wall and with each said overlapping portion of each cross-like divider member further including a notch along a side edge thereof for creating an interengagement between said portions to increase the structural rigidity of said central wall, each said overlapping portions further having an arcuately shaped side edge portion disposed above said notch to facilitate the interengagement of said portions during erection of the carton, such that said cross-like divider members cooperate with each other and with said carton walls to form a six-cell configuration.
